Revelation 12:10-11

10Then I heard a loud voice in heaven saying, “The salvation and the power and the kingdom of our God, and the ruling authority of his Christ, have now come, because the accuser of our brothers and sisters, the one who accuses them day and night before our God, has been thrown down.

11But they overcame him by the blood of the Lamb and by the word of their testimony, and they did not love their lives so much that they were afraid to die.
